Hellllp!!!! I put my tune back to stock with the preditor tuner and now my shift are all crazy. I just drove home from work and it was fine it started after i detuned it. I'm getting a really bad shutter when it's trying to shift. I'm going to try and put the tune back on and see if that helps

I would scan it to see if there is any codes, if the transmission throws any codes it will go into a high pressure lockup state and act just like you are describing. Or the tune you reverted back to doesn't any trans files so it is just running blind.

I switched it back to the 93 tune and it shifted fine...I then switched back tithe stock tune and it's shifting normal again "whew" my ***** fell too my ankles when it shifted like that haha but I don't understand why it happened in the first place I feel like I took some miles off of the already short trans life

yeah, the predator would have nothing to do with the tranny... doesn't communicate with the TCM at all, so it can do absolutely nothing to it....
there was something else whacky goin' on there...

Everything seems to be good now. Im taking my car in on tuesday to get the Oil pan shield installed and then im putting the tune back on. I hate the way DOD makes the car drive I keep thinking something is going wrong when it turns on.
